[Networker] Query in Staging from adv_file
2008-08-18 13:52:27
The backup I am taking is from a database using NMO, I will have approx 20 save
sets. Below is the answers for ur questions
How many LTO2 drives do you have access to from the Networker server?
The adV_file device is give to a Storage Node and this SN has visiblity of
5 tape drives.
How are the LTO2 drives connected to the Networker server? SCSI, Fibre, etc.
FC
What is the Network architecture between the db server and the networker
server? 80MB/sec sounds like 2-3 teamed GBit NICs.
From the client I have IPMP configured and on the Storage Node I
have Solaris Trunking enabled.
What is the adv_file disk architecture? What kind of local disk access metrics
do you see on it? Read/Write MB/sec?
I have around 10TB of storage space taken from a SAN box and in
the OS side Solaris ZFS is used. I am able to see the load is equally
distributed among all the disks.
I have created a single file system of 10TB size and have created few
directories under this and made each of them as adv_file device. And configured
the parallelism to 4 per adv_file. In our environment all the RMAN backup is
configured with 4 channels, so that each client will use one adv_file device.
Also during staging each adv_file will take one physical drive.
I am still finding out a better solution.
